Definitions

  • the invention relates to a method for producing a double-walled cup in which a sleeve-shaped outer shell made of a paper material on a prefabricated inner cup is axially slid and fixed, wherein the sleeve-shaped outer shell is formed before pushing from a flat blank by connecting the ends of the blank, and wherein the ends of the blank are joined by an adhesive applied in limited areas of the outer shell.
  • the invention further relates to a cup produced by this method.
  • a method of this kind is by the DE 198 40 841 A1 State of the art.
  • a cold glue is applied as an adhesive in a limited area.
  • the ends of the blank are glued together to form a sleeve.
  • This sleeve is pushed as an outer jacket onto a prefabricated inner cup. Due to the stability of the sleeve-shaped prefabricated outer sheath, a substantially annular air space can be formed between the outer sheath and the inner sheath of the cup, wherein outer sheath and inner sheath do not touch along the air space.
  • the thickness of the substantially annular air space can be increased by a sudden expansion in the upper region of the inner shell, so that the insulating effect of the cup is improved.
  • the outer shell can be made from a very inexpensive paper material.
  • the blanks for the outer jacket may consist of single-layer paper material without additional plastic coating.
  • the outer casing does not come into contact with the liquid to be filled. So it's one uncoated paper material sufficient to achieve the insulating effect of the double-walled cup.
  • the gluing of the ends of the blank with cold glue limits the operating speed of the manufacturing device, since the cold glue takes a relatively long time until it sets. The ends of the blank must therefore remain compressed relatively long, so that the adhesive bond does not dissolve again immediately.
  • the processing of cold glue is expensive, since cold glue often has viscosity fluctuations, which prevent precise metering of the applied amount of glue. Excessive application of glue causes contamination of the production machine, so that the machine often has to be shut down for cleaning.
  • the invention has for its object to provide an improved method for producing a double-walled cup.
  • thermoplastic material is used as an adhesive when connecting the ends of the blank to a tubular outer shell.
  • thermoplastic material such as a hot melt adhesive or a so-called hot melt
  • a hot melt adhesive can be applied very precisely with defined viscosity in limited areas of the outer shell and binds when compressing the ends very quickly.
  • the speed in the production of the double-walled cup can be greatly increased.
  • the manufacturing machine is not contaminated by imprecise dosed adhesive, so that the frequent cleaning work accounts.
  • the hot melt adhesive is applied to limited areas of the blank in liquid form prior to joining the ends of the blank into a tubular outer shell. The ends of the blank need only be compressed for a very short time to be securely and stably glued.
  • a sealing wax can also be used as the thermoplastic material.
  • the sealing lacquer can be applied to the flattened blank in a step which precedes the actual production process of the double-walled cup or at least in a step upstream of the shaping of the outer casing.
  • the sealing lacquer may be applied in the form of a strip to one end of the blank before the blank is fed to the double-walled cup making machine.
  • the application of the sealing wax can be done for example in a printing press. The sealing wax is thus on the flat blank already solidifies and does not hinder the feeding of the blank in the Becherherstellmaschine.
  • the sealing wax When connecting the ends of the blank to the sleeve-shaped outer jacket, the sealing wax is reheated so that the ends are glued together after brief juxtaposition.
  • Applying sealing wax prior to feeding the blanks for the outer shell in the Becherherstellmaschine has the great advantage that in the Becherherstellmaschine no applicators and metering devices for adhesive must be present. Any contamination of the Becherherstellmaschine by adhesive can be effectively prevented.
  • the sealing wax can be applied very sparingly in limited areas of the outer shell, where it is needed for connection.
  • the attachment of the sleeve-shaped outer jacket to the inner cup can also be effected by a thermoplastic material as an adhesive. For this purpose, a strip of sealing wax can be applied along an arcuately curved edge of the blank.
  • sealing wax as a thermoplastic material for bonding the outer shell
  • devices for joining the ends of the blank can be used, as are similarly used for joining the inner shell in the manufacture of the inner cup.
  • the blanks for the outer jacket with the sealing lacquer printed in the limited areas can in principle be processed in the same way as the polyethylene film-coated blanks for the inner cup.
  • Such sealing devices are known per se, so that a detailed description is omitted here.
  • the inner cup can be designed as desired per se.
  • it can consist of a paper material.
  • the inner cup can also be a plastic cup.
  • the outer sheath different configurations are possible.
  • the outer jacket may for example consist of a smooth paper material or of a corrugated paper material.
  • thermoplastic material as an adhesive for the sleeve-shaped outer jacket is particularly advantageous when the inner cup has a sudden diameter change in the form of a shoulder in the upper region of the inner jacket.
  • the sudden expansion is located just below a mouth roll of the inner cup, so that a narrow area for fixing the outer shell remains between the expansion and the mouth roll.
  • This area for fixing the outer shell is usually above the level of the hot liquid to be filled into the cup.
  • Below the abrupt change in diameter there is a substantially annular air space between the outer jacket and the inner jacket, along which outer jacket and inner jacket do not touch.
  • connection point extending in the cup longitudinal axis of the ends of the blank of the sleeve-shaped outer sheath is also spaced from the inner sheath in contact with the hot liquid by this air space.
  • thermoplastic material compounds on the outer shell dissolve again by the filling of hot liquid in the double-walled cup.
  • EP 1 785 370 A1 describes the use of a hot melt adhesive for provisionally securing an outer jacket to an inner cup.
  • the outer sheath is not glued to a sleeve, but wound directly around the sheath of the inner cup and glued there.
  • a cold glue is applied to the outer jacket in addition to the hotmelt adhesive.
  • the disadvantages of using cold glue have already been described above.
  • the cold glue is in the execution of EP 1 785 370 A1 necessary, because the connection made by the hot melt adhesive between the inner shell and the outer shell during the filling of hot liquid in the cup can solve again and there is a risk that the outer shell by the residual stress of the paper material jumps up and falls from the inner cup.
  • the in FIG. 1 shown double-walled cup 1 consists essentially of an inner cup 2 with a fillable interior 3 and an outer shell 4.
  • the fillable interior 3 of the inner cup 2 is formed by a conical inner shell 5 and a cup-shaped bottom 6.
  • the open side of the cup-shaped bottom 6 is arranged so that it faces away from the filling opening of the cup 1.
  • the bottom 6 is connected with its wall in the region of the smaller circumference of the inner shell 5 liquid-tight with this by a frame 7.
  • the material of the inner shell 5 is wrapped around the wall of the bottom 6 and hammered inwards.
  • the inner shell 5 has at its upper edge, ie in the region of the larger circumference, an outwardly beaded mouth roll 8, which surrounds the filling opening.
  • the property "conical” of the inner shell 5 is understood to mean that the inner shell 5 in the in FIG. 1 shown longitudinal section of the mouth roll 8 tapers to the bottom 6. It is irrelevant which shape of the inner shell 5 has in cross section.
  • the inner shell 5 may be circular in cross section, for example, oval or rectangular with rounded corners.
  • the inner cup has a truncated cone-like shape, while in the case of a rectangular cross-section it has a more truncated pyramidal shape.
  • the frame 7 may preferably have an outwardly projecting widening 9 at least in a region along its circumference.
  • the widening 9 may alternatively extend only over a lower portion of the frame 7.
  • a lower edge of the widening 9 on the frame 7 forms a base for the cup 1.
  • the cup is in use on its footprint, which is increased by the expansion 9. As a result, tilting of the cup 1 is difficult.
  • the expansion 9 is preferably designed circumferentially along the circumference of the frame 7.
  • the frame 7 is a very important element of the cup 1.
  • the frame 7 is necessary for the connection between the inner shell 5 and the bottom 6.
  • the material of the bottom 6 is with the material of the inner shell 5 in the region of the frame 7 glued or sealed to be liquid-tight at least for a certain period of time.
  • the term "paper material" from which the bottom 6 and the inner shell 5 is made can be understood to mean different materials which have at least one layer of paper, paperboard or cardboard.
  • the material may comprise one or more layers of plastic and / or aluminum.
  • the paper material is on the side bounding the interior 3 with a thin plastic layer, preferably made of polyethylene, coated.
  • the frame 7 is an essential design feature that can not be waived.
  • the inner shell 5 may advantageously have a sudden change in size in the form of a shoulder 10 in the area below the mouth roll 8, which is seen from the bottom 6 to the mouth roll 8 as a sudden cross-sectional widening. Between the mouth roll 8 and the shoulder 10 is located on the outer surface of the inner shell 5, a contact surface 11 for the outer shell. 4
  • a bead 12 can be formed in the inner casing 5 as a means for stacking, on which the widening 9 of the frame 7 of a similar cup 1 to be inserted into the inner space 3 is stacked. It is thereby prevented that the stacked cups 1 wedged into each other.
  • the outer jacket 4 can be designed differently. Two possible designs of the outer shell 4 are in the FIGS. 3A and 3B shown. In FIG. 3A is to recognize a smooth outer shell 4, which surrounds the inner shell 5 at a uniform distance. In FIG. 3B a corrugated outer shell 4 is shown. The substantially annular air space 13 thereby has an alternating width. Depending on the requirements, it may be provided that the regions of the outer jacket 4 closest to the inner jacket 5 still have a small distance from the inner jacket 5 or, alternatively, contact the inner jacket 5, so that the outer jacket 4 is supported on the inner cup 2 and improved stability of the double-walled jacket Bechers 1 is created.
  • a prefabricated inner cup 2 is used in a manner known per se.
  • This prefabricated inner cup 2 is connected to a sleeve-shaped outer casing 4, so that a substantially annular air space 13 is formed between the outer casing 4 and the inner casing 5 of the cup 1, along which outer casing 4 and inner casing 5 do not touch.
  • the widening 9 can be formed before or after pushing on the outer jacket 4.
  • the air space 13 has a good insulation effect, so that the double-walled cup 1 can be easily held in the hand even with a filled in the interior 3 very hot liquid.
  • an inwardly directed curl 14 is provided, with which the outer shell 4 is supported on the inner cup 2.
  • the blank 15 has approximately the shape of a segment of a circular ring with two arcuate edges 16 and 17 and two straight ends 17 and 18.
  • the blank 15 for the outer shell 4 consists of an uncoated paper material, because the outer shell does not come into contact with the liquid to be filled when using the cup 1.
  • the double-walled cup 1 is commonly used as a disposable cup for hot drinks and disposed of after a single use. The less plastic the cup 1 contains, the better the paper material is recyclable.
  • the blank 15 is wound around a conical mandrel and the end 18 is connected in an overlapping manner to the end 19.
  • a thermoplastic material is applied to the end 18 in a limited area as an adhesive.
  • the limited area at the end 18 of the blank 15, in which the thermoplastic material is applied as an adhesive, is in FIG. 2 characterized by the hatching provided with the reference numeral 20.
  • thermoplastic material for joining the ends 18 and 19 of the blank 15 to the tubular outer shell 4
  • two different thermoplastic materials are particularly suitable as an adhesive.
  • a hot melt adhesive is applied in liquid form prior to joining the ends 18 and 19 to the limited area 20 of the blank 15.
  • a metering device can be provided which applies the hotmelt adhesive to the blank 15 through a nozzle at a defined temperature.
  • the end 19 is placed over the area 20 at the end 18 and pressed it. In this case, the hot melt adhesive cools down and the ends 18 and 19 are securely connected to each other within a very short time.
  • a sealing wax can be used as a thermoplastic material.
  • the sealing wax is printed with a printing press on the flat blank 15 in area 20 and solidifies there.
  • Prefabricated blanks 15 with the applied sealing wax in the area 20 can then in the production of the double-walled Bechers 1 are processed in the Becherherstellmaschine without in the Becherherstellmaschine another adhesive application is required.
  • the blank 15 with the previously applied sealing wax in the region 20 is wound around a mandrel, wherein the end 19 is placed over the region 20 at the end 18. Under brief heat, the ends 18 and 19 pressed against each other, so that the sealing wax is reheated, and thereby the end 19 bonded to the end 18.
  • the inwardly directed curl 14 is formed at the arcuate edge 17, and the sleeve-shaped outer shell 4 is removed from the mandrel. Subsequently, the sleeve-shaped outer jacket 4 is pushed in the axial direction onto the prefabricated inner cup 2 from below and fastened to the inner cup 2. The attachment of the outer shell 4 on the inner cup 2 is effected in that a region at the upper edge 16 of the outer shell 4 rests against the contact surface 11 of the inner shell 5.
  • the attachment of the sleeve-shaped outer sheath 4 on the inner cup 2 can also be carried out differently.
  • the hotmelt adhesive is either applied in liquid form to the outer shell 4 in the region of the upper edge 16 or applied to the contact surface 11 of the inner cup before the outer shell 4 is pushed onto the inner cup 2 from below. After pushing the outer shell 4 on the inner cup 2, the outer shell 4 can be pressed with the inner shell 5 in the area between the shoulder 10 and the mouth roll 8.
  • a limited area 21 is provided on the blank 15 along the arcuate edge 16 analogous to the area 20 at the end 18, is applied in the sealing wax.
  • the area 21 is located after connecting the ends 18 and 19 of the blank on the inside of the sleeve-shaped outer shell 4 and comes after pushing the outer shell 4 in contact with the contact surface 11 of the inner cup 2.
  • the outer jacket 4 and the inner jacket 5 are pressed and sealed in the region 11 with the sealing wax in between under the action of heat.
  • a pressing of the outer shell 4 and the inner shell 5 in the region 11 with the intervening thermoplastic material as an adhesive can be performed differently depending on the requirements.
  • a over the entire circumference of the cup. 1 be continuous pressing, so that a stable connection between outer shell 4 and inner cup 2 is formed.
  • a hotmelt adhesive for example, it may be sufficient to apply it only in a punctiform manner before the outer shell 4 is pushed onto the inner cup 2 from below.
  • sealing wax When sealing wax is used, provision may be made for a sealing lacquer to be applied only in partial regions of the region 21 along the arcuate edge 16 of the blank 15. The amount of thermoplastic material required for the production of the double-walled cup 1 can thereby be minimized.
